摘要：
Compositional, frequency, and temperature studies of impedance and electrical conductivity in (Ag3AsS3)(x)(As2S3)(1-x) superionic glasses and composites were performed. Frequency range from 10 Hz to 3 x 10(9) Hz and temperature interval 300-400K were used for the measurements. Compositional dependences of electrical conductivity and activation energy are analyzed; the most substantial changes are observed with the transition from (Ag3AsS3)(0.4)(As2S3)(0.6) glass to (Ag3AsS3)(0.5)(As2S3)(0.5) composite. With increase of Ag3AsS3 content, the investigated materials are found to have crystalline inclusions and show the two-phase composite nature. Addition of Ag3AsS3 leads to the increase of electrical conductivity whereas the activation energy decreases. (C) 2014 AIP Publishing LLC.
